1351 Clear glass Desiccator with porcelain plate Product Description It is a non-vacuum desiccator, and therefore has no stopcock. The sturdy glass top fits easily on the thick lip of the desiccator, and features a knob handle for removing or replacing the lid. The lips of both the lid and the desiccator itself are ground glass, and should be greased with petroleum jelly before use. In addition to helping create an air-tight seal, the grease also helps cushion the lid when it is set down in place. To help prevent damage from being set down too forcefully, the lid can be carefully slid on, or off, of the desiccator once greased. Desiccators can be used, though not exclusively, for preserving moisture-sensitive items, protecting hygroscopic or water-reacting chemicals, as well as removing traces of water from samples that need drying. There are 8 sizes available : 120 mm desiccator, 150 mm desiccator, 180 mm desiccator, 210 mm desiccator, 240 mm desiccator, 300 mm desiccator, 350 mm desiccator, 400 mm desiccator.

With a procelain plate 1354 Clear glass Vacuum Desiccator with porcelain plate Product Description Desiccators are sealable enclosures containing desiccants used for preserving moisture-sensitive items such as cobalt chloride paper for another use. A common use for desiccators is to protect chemicals which are hygroscopic or which react with water from humidity. The contents of desiccators are exposed to atmospheric moisture whenever the desiccators are opened. It also requires some time to achieve a low humidity. Hence they are not appropriate for storing chemicals which react quickly or violently with atmospheric moisture such as the alkali metals; a glovebox or Schlenk-type apparatus may be more suitable for these purposes. Desiccators are sometimes used to remove traces of water from an almost-dry sample. Where a desiccator alone is unsatisfactory, the sample may be dried at elevated temperature usingAbderhalden's drying pistol. There are 7 sizes available : 150 mm desiccator, 180 mm desiccator, 210 mm desiccator, 240 mm desiccator, 300 mm desiccator, 350 mm desiccator, 400 mm desiccator.

GFT-01 Flex Durability Tester Background A pivotal characteristic of flexible barrier materials is their resistance to repetitive strain, commonly referred to as flex durability or Gelboflex resistance. A strong resistance to flex cracking is paramount as it reduces the likelihood of package perforation during distribution, thus ensuring package integrity. Application The Flex Durability Tester, also recognized as Gelboflex, evaluates the capability of materials such as films, composites, and coating films to endure repetitive strain. It quantifies flex failure by identifying potential pinholes in the sample structure. Optimal flex crack resistance is crucial as it diminishes the possibility of packaging developing perforations during distribution, thereby upholding the package's integrity throughout its journey. This aspect is indispensable for safeguarding the contents within. Standards Our Flex Durability Tester adheres to the ASTM F392 standard for assessing the flex durability of flexible barrier materials. Sampling and Motion Within the Flex Tester, a sample measuring 200 by 280 mm is securely fastened to the mandrels. The flexing process entails a combination of twisting and horizontal compression, subjecting the film to these actions repeatedly. Specifically, the setup initiates a twisting motion spanning 440 degrees within the first 90 mm of the stroke, followed by a linear horizontal motion of 65 mm. This entire cycle operates at a speed of 45 cycles per minute. Users can choose from five pre-programmed test conditions: - Mode A Full flex for 1 hour (2,700 cycles) - Mode B Full flex for 20 minutes (900 cycles) - Mode C Full flex for 6 minutes (270 cycles) - Mode D Full flex for 20 cycles - Mode E Partial flex for 20 cycles Technical Features Our system boasts PLC control complemented by an intuitive HMI touch screen interface. It offers five standard test modes and encompasses four test stations. Users benefit from the ability to swiftly switch between long and short stroke modes. Furthermore, the system facilitates the selection of test conditions A, B, C, D, and E. Additionally, it features a microprinter for seamless data output. Main Parameters Flex Frequency 45 /minute Flex Angle 440 (90 mm) or 400 (80 mm) Capacity 2.5 N.m Horizontal Stroke 155 mm or 80 mm Stations 4 Sample Size 280 mm x 200 mm Power 110~220V

This Sharples Strain Viewer is already in worldwide use for the quality control of PET preforms. The advantages of our PET preform Strain Viewer are : - 1. Crystallinity is readily identified. 2. Not only can the molecular birefringent flow lines (fringes) be seen in colour but the black isoclinic lines are visible when the preform axis are parallel to the polarising axis of the viewer. The isoclinic lines indicate the directions of the molecular orientational strains. 3. A special and removable stage is provided to rapidly obtain the correct alignments of the preforms when viewing. For observations of the fringes the preforms are aligned at 45 degrees to the polarising axis and at 0 degrees to view the black isoclinics. The stage allows for the rotation of the preforms whilst viewing. Sodium light is also provided, in addition to white light, for the examination of coloured preforms or completed bottles. The lamphouse is fan cooled. Data: Viewing field:..............260 x 260mm Overall size:...............445 x 280 x 280mm Mains voltage:............220/240v or 110v.
